in the drawing. '2 represents thedirame ol' the. machine. having' carrying and traction wheels I) and an internal combustion engine. i (it suitable type thereon. The frame forming of the machine is preferably provided with is secured by pins In this casting a rearwardly projecting stud 9 is preferably secured. A yoke 10 has a sleeve 11 thereon to receive the stud 5) on. which the yoke is tree to rock but is limited in its movement by a pin 12 which projects into a slot. 13 in said sleeve and by a lug 1%- which projects into a recess 15 in the casting Y. The pin 12 also has the further function of holding the sleeve and yoke in place on the stud. The outwardly projecting arms of the, yoke 10 have vertical sockets 16 therein to receive the ends of rods 17" on which caster wheels 18 are mounted, said rods being free to rock on. a vertical axis in said sockets to allow the wheels to accommodate themselves to the change of direction in the movement of the machine. The yoke is also preferably provided on each side of its axis with a V-shaped socket in into which the upwardly turned forward ends of draft rods 20 are inserted. Said ends have bearings in the lower Walls of the socket and project upwardly through the same and are preferably connected with the corresponding upwardly turned rear ends of said rods means of bars 21 which serve.

to hold the draft rods in place in the sockets 19. The rear upwardly turned ends of the rods 20 are preferably provided with sleeves U-shapeo clamp member is mounted on .ach sleeve 22 and is provided witlra clamping; screw E l between which and a block seated on the sleeve 22 an implement carrying bar or pipe 26 is inserted (see Fig. 9). The clamping screw 24 bears on the wall of the pipe or other support for the. implements and this pressure is'in turn transmitted to the block in the sleeve so that when the screw is tightened the pipe and the sleeve will be locked but the rods 20 will be free to oscillate in the sleeves to acconinualate themselvcsto the diti'erent positions of the in'iplements. This same form of clamp ispretcrably used on the bar or pipe supporting the iu'iplenients for securing the shanks thereof. These shanks may be flat, round. or polygonal in cross section, as preferred. and may support implements of various shape, as indicated at 28 and the shanks being inserted through the holes in the clamp member 23 in place of the sleeve the block 25 engaging the may be raised or lowered. according to the depth it is desired to cultivate or plow -and the character of the soil in which the machine is working. By providing a clamp of this type we adapt the machine for use with a great variety of ground-working implements, some of which may have round shanks while others may have square or polygonal shanks with irregular faces, the clamp adapting itself to any style of shank which may be used. Suitable clamps 30 are pivoted on the ends of the yoke 10 by means of bolts 1'? and have polygonal sockets 31 therein to receive a bar 32, also polygonal in Ci'VJe section which is fitted into said sockets and secured therein by suitable means, such as set screws 33. Clamps 30 are mounted on the bar 32 and have vertical bearings for the spindles 17 of the caster wheels, said clamps having, recesses therein to receive collars 34; mounted on said spin dies by means of which the spindles may be adjusted vertically in said clamps to raise or lower the caster wheels. The clamps 30 are secured onthc bar by set. screws Iii-l correspontlin to those described with reference to the clamps 0. By loosening thesc set screws the caster wheels can be moved back and forth on the ha and may be set out a conside 'ablo distance on each side of the machine to adapt it, .ior working on rough or unevengnaind. The collar 3i. while holding the caster wheel spindles against vertical movement, permits oscillation thereof and the movement oi. the caster wheels to follow the direction of travel of the machine.

We have shown small groumlqvorki11;: or cultivating tools mounted on the d raft bar or carrier of the machine, butdo not confine ourselves thereto, as many ditl'erent types or styles of tools may be used in place of those shown.

In this machine we prefer to depart: from the single type of steering post illustrated in the Peters patent above. referred to and use two p0 in parallel relation and spaced apart snllicientl so that the operatmr will have a clear vision between the posts of the re of p ants over which the machine is 'itz ng ese posts we predescri oed mecha sting; pit" led at 3% on the casting; by means (a? a suitable horizontal pivot. This casting has sockets 37 therein in which post's are inaer'ed. r are 39 are "reared on said posts within said sockets by set screws to. These collars serve to hold the poets in place in their sockets, While permitting them to rock and shift; the ground working innglenientis from side to side, the connections with such implements operating to limit, suitably the rocking or rotary enient of the costs. We prefer also to nine 0 Without making use of the feature of shift.- ing the ground-working implements from side to side through the rotary aiovenient oi the steering posts. The e l r ends of the posts are preferably provided with handle bars :lrl: terminating in hand grips l5, a connection 46 being provided between the bars to maintain the parallelism thereof. This connection 46 may be a link or rod. as showin or any other suitable. means for 1.. ntaiir ing theposts in parallel relation. i ljacent to the hand grips are the lever devices and 4:8 by n'ieans oi which the clutch oi' t engine and the iced ot" the gas thereto is controlled. Each of the posts iutcrnualiz'ite its ends is provided with a cl links 50 are secured to said amp ill and clamps at one end and adjustably connected b v bolts 51 avith similar links 5; which are attached to the upper rear ends of the rods by bolts 323i l pon looseningthe lefllifi 51. the links may be ad usted one upon the other to vary the. position of the si'thtliiil' posts with respect. i 'l 1 k i Vi 10 t 1c agiiru lltld llllplLllldlltf-a ace the posts are rocked on a longitudinal axis, the implements will he mo ed tron: ne o s de in an upright. positioin swing'ir j ot'al ominertion between rods 20. i preferably oi." the type sho the These clamp: on

the machine or renaming ii A. rot ary ad ustment of the clamps i tween the I it) normally resists ti: of the steering working implements with a yielding 'pressu..:e. adjusted to correspond to tl e adjust the links 50 and 52.

ll hen pressure is applied to the steering posts and the implements are forced into the soil, the spring 56 will ,'iel .lingly resist such downward pressure and enable the operator to maintain quick control over the implements in depressing or elevating them and in a measure relieve him from the vibration or which a rigid connection might transmit from the draft rods to the handle oars. If desired, the compression spring may he removed and an ordinary cotter pin inserted into one of the holes of the bar to form a fixed support and prevent relative downward movement of the bar and the steering posts.

' In the operation of the machine, the handle bars are grasped and the steering posts rocked on a longitudinal axis to snift the ground-working implements from side to side, as may be desired, while lateral pressure or movement of the steering posts from one side to the other will rock the machine on a vertical axis and steer it between or over the rows of plants. The operator, travling behind the machine, will have a clear vision offthe plants and atthe same time can direct the implements in such a manner as to stir up the soil close to the plants without danger of damaging them. Furthermor I as in the Peters patent, when the implements are-in the soil they will be held against lateral movement during the swinging of the machine frame sothat the steering device may be oscillated laterall to guide the ma chine Without affecting the movement of the ground-working implements.

It will be observed that the yoke '10, the draft rods 20 and the bars 21, together form what may be designated as an auxiliary frame, supported mainly upon the caster wheels 18, and carrying and supporting in turn the ground-working implements. The stud 9 forms a longitudinally extending zlXlS or pivot pin upon which the main frame 2' and the auriliar vgframe, made up of the parts specified, are adapted to oscillate with respectto eachother, without interfering; with the reciprocating or side to side movement of the carrying bar 26 and the ,Q'l'iflllltl- Working implements. The auxiliary frame thus has a flexible connection with the main frame and can adjustitself to iuei-uialities ot the soil over which the machine is moving.

As the steering posts arehinged to the casting 7, which in turn is conne: ted to the frame 2 of the machine, and as these steerin'g posts arealso-connected through the links with the carrying bar 26 to which theground-working implements are secured,

it follows that by raising the handle ends of the steering posts, the ground-working inn plem'ents may he raised from the soil and by depressing; said handle ends of said posts said implements may be forced downward or farther into the soil.

By swinging the handle ends of the steer ing posts laterally, the main frame of the machine, its supporting wheels and theparts supported by said frame are turned in the direction 111 which the operator desires the machine to travel. iv rotating said steering posts on their axes the har ill; and the groluni-working implements carried lrv said bar are reciprocated laterally of the line of travel of the machine.

The operator by hearing down on one of the handle bars ma rotate the post on which that bar is mounted on its longitudinal axis and through the rigid mounting of the liars on the posts and their pivotal connection with the gromnhworlring implements. the said implements will be shifted laterally and a corresponding movement will bc imparted to the other post and its handle bar. The implements may. therefore, he shifted in lo tating' either or both posts as desired, and in either case one arm will swing downward and the other upward while the posts will rotate simultanmuslv in the same direction through the rigid connection of the bars 50 and 52 with the posts and their pivotal connection with the implements.
